Computer Memory Solutions CM5126412800SOSRL 4GB DDR3L 1600MHz SODIMM memory upgrade Lenovo Thinkpad E450

Compatible Lenovo Thinkpad E450 upgrade

This 4 GB DDR3L SODIMM is built specifically for the Lenovo Thinkpad E450 laptop. It delivers 1600 MHz speed at 1.35 V with CL11 timing in a single 204-pin module. The stick is unbuffered, non-ECC and uses major-brand chips backed by a limited lifetime warranty from Computer Memory Solutions.

Suits owners adding one 4 GB stick.

Buyers wanting to add a single 4 GB module to an empty slot or replace a failed stick will find this a direct fit. Users who need a matched pair for dual-channel performance or who require the full 16 GB maximum capacity should look at a 2 x 8 GB kit instead. The 1Rx8 rank and 1.35 V operation match the factory specification exactly.

DDR3L 1.35 V voltage decides fit

The critical specification is the 1.35 V DDR3L voltage; standard 1.5 V DDR3 modules will not operate correctly in this system. Confirm the laptop requires low-voltage memory before ordering, as the 1600 MHz PC3L-12800 rating and 204-pin SODIMM form factor depend on that voltage.
